Can someone solve these 3 circuits for me? These are from an old exam and I need to see the solutions. Maybe it will help for my next one, so plz circuit1: R=2kOhm, C1=6uF, C2=2uF, C3=1uF, V=17V Calculate the time constant of the circuit and also the voltage of every capacitor when I=4mA(current that runs through V1) circuit2: Calculate voltage Vo of this circuit. R1=1kOhm, R2=2kOhm, R3=200Ohm, VEE=10V, aDC=1. Diodes are ideal, silicon. circuit 3: Calculate the amperage I on resistor R2.
